DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0036] The detailed embodiments of the present invention are
disclosed herein. It should be understood, however, that the
disclosed embodiments are merely exemplary of the invention, which
may be embodied in various forms. Therefore, the details disclosed
herein are not to be interpreted as limiting, but merely a basis
for teaching one skilled in the art how to make and/or use the
invention.
[0037] With reference to the various figures, a modular speaker
system 10 is disclosed. The speaker system 10 includes a base
assembly 100 to which a plurality of auxiliary speaker assemblies
200, 300 may be secured in a manner creating a customized, modular
speaker system 10 adapted for creating a customized modular sound
reinforcement system, optimized for the power requirements and
acoustic criteria of each specific performing (performance)
environment. As will be explained in the following disclosure, the
present speaker system 10 is adapted for a variety of uses through
its modular nature, as well as its ability to permit ready assembly
and disassembly.
[0038] The base assembly 100 includes a longitudinally extending,
cylindrical, central support member 102 and a support leg 104
extending therefrom in a manner supporting the central support
member 102 in a generally upright configuration. As will be
discussed below in greater detail, the support leg 104 is
cylindrical and provides a passageway for coupling the various
drivers used in accordance with the present invention with a power
source. The support leg 104 is pivotally secured to the central
support member 102 allowing the support leg 104 to collapse onto
the central support member 102 for compact storage when the present
speaker assembly 10 is disassembled.
[0039] The central support member 102 includes a first end 106 and
a second end 108. The first end 106 is provided with a planar
support plate 110 shaped and dimensioned to sit upon a support
surface 112 supporting the base assembly 100 in a stable manner
when used in conjunction with the support leg 104. The second end
108 of the central support member 102 includes a coupling member
114 shaped and dimensioned to selectively receive and support an
auxiliary speaker assembly 200. In accordance with a preferred
embodiment, the coupling member 114 is a female coupling member
shaped and dimensioned to receive a similarly shaped male coupling
member 214 extending from the auxiliary speaker assembly 200 in a
manner discussed below in greater detail. The female and male
coupling members 114, 214 may further be provided with selective
locking structures for adding to the stability of the connection
between the central support member 102 and the auxiliary speaker
assembly 200. In accordance with a preferred embodiment of the
present invention, the female and male coupling members 114, 214
are provided with bayonet type locking structures, although those
skilled in the art will appreciate other coupling mechanisms may be
employed without departing from the spirit of the present
invention.
[0040] A first woofer 116 and a second woofer 118 are secured to
the base assembly 100. Each of the first and second woofers 116,
118 includes a base 120, 122 shaped and dimensioned to sit upon a
support surface 112 in a stable manner taking advantage of the mass
of the woofers 116, 118 to significantly lower the whole assembly's
center of gravity. As such, the first and second woofers 116, 118
support themselves upon the support surface 112 while also adding
to the stability of the base assembly 100 by functioning as
additional legs extending from the central support member 102. This
adds stability to the entire speaker assembly 10 and allows for the
attachment of additional auxiliary speaker assemblies in the manner
discussed below.
[0041] First and second coupling arms 124, 126 extend between the
central support member 102 and the respective first and second
woofers 116, 118. Each of the first and second coupling arms 124,
126 includes a first and a second end. The first ends 128, 130 of
the first and second coupling arms 124, 126 are coupled to the
central support member 102 via a swivel joint 132, 134 allowing
free movement therebetween and the second ends 136, 138 of the
first and second coupling arms 124, 126 are similarly coupled to
the respective first and second woofers 116, 118 via a swivel joint
140, 142 allowing free movement therebetween. The use of swivel
joints 132, 134 in connecting the first and second coupling arms
124, 126 to the central support member allows the woofers 116, 118
to be folded close to the central support member 102 during storage
and moved outwardly as shown in FIGS. 1, 2 and 3 when the speaker
assembly 10 is placed into use. It is contemplated in accordance
with a preferred embodiment of the present invention the swivel
joints are of a ball and socket type construction and are
maintained in desired orientations through the implementation of
various locking structures (not shown) known to those skilled in
the art. For example, the locking structure may take the form of
locking pins, compression members, frictional resistance members,
etc.
[0042] A base member amplifier 144 is mounted within the central
support member 102 and drives the first and second woofers 116,
118. Those skilled in the art will appreciate the base member
amplifier may also be provided with various signal processing
components known to those skilled in the art. The base member
amplifier 144 is mounted within the central support member 102 and
is covered by a removable plate 145 for ready access by a user of
the present speaker assembly 10. It is appreciated the plate may be
slidingly or pivotally secured to the central support member to
allow access to the base member amplifier, while not requiring that
the plate be fully removed from the central support member thus
preventing the possibility that the plate might be misplaced after
being removed from the central support member.
[0043] The base member amplifier 144 is electrically coupled to the
respective first and second woofers 116, 118 via wires (not shown)
extending from the base member amplifier 144, through the central
support member 102, through the respective first and second
coupling arms 124, 126 and into the connections of the first woofer
116 and the second woofer 118.
[0044] The base member amplifier 144 further includes source
connections 146, a power connection 148 and various control members
149. The source connections 146 allow for one to attach various
sound sources directly to the base member amplifier 144. The source
signals are then processed by the base member amplifier 144 using
conventional sound processing techniques and distributed to the
various drivers making up the present speaker assembly 10. The
power connection 148 of the base member amplifier is linked to an
external connection point 150 within the support leg 104 via a wire
151 for connection to a remote power source.
[0045] As discussed above, the base assembly 100 is shaped and
dimensioned for supporting one or more auxiliary speaker assemblies
200, 300. The first auxiliary speaker assembly 200 includes a
longitudinally extending, auxiliary support member 202 having a
first end 206 and a second end 208. The first end 206 includes a
coupling member 214 shaped and dimensioned for selective engagement
with the coupling member 114 at the second end 108 of the central
support member 102. More particularly, and as discussed above in
accordance with a preferred embodiment of the present invention,
the coupling member 214 at the first end 206 of the auxiliary
support member 202 is a male coupling member shaped and dimensioned
for receipt within the female coupling member 114 at the second end
108 of the central support member 102 of the base assembly 100.
[0046] The second end 208 of the auxiliary support member 202
includes a coupling member 215 shaped and dimensioned to
selectively receive and support an additional auxiliary speaker
assembly 300. As with the respective male and female coupling
members 214, 114 of the auxiliary support member 202 and the
central support member 102, and in accordance with a preferred
embodiment of the present invention, the coupling member 215 at the
second end 208 of the auxiliary support member 202 is a female
coupling member shaped and dimensioned to receive a similarly
shaped male member 315 extending from another auxiliary speaker
assembly 300. As with the connection of the base assembly and the
auxiliary speaker assembly, the male and female coupling members
315, 215 may further be provided with selective locking structures
for adding to the stability of the connection between the auxiliary
support member 202 and the auxiliary speaker assembly 300.
[0047] The auxiliary speaker assembly 200 includes a first support
arm 224 connecting a first driver 216 to the auxiliary support
member 202 and a second support arm 226 connecting a second driver
218 to the auxiliary support member 202. Each of the first and
second support arms 224, 226 includes a first and a second end. The
first ends 228, 230 of the first and second support arms 224, 226
are coupled to the auxiliary support member 202 via a swivel joint
232, 234 allowing free movement therebetween and the second ends
236, 238 of the first and second support arms 224, 226 are
similarly coupled to the respectively first and second driver
assemblies (for example, and in accordance with a preferred
embodiment, which is composed of a midrange driver and tweeter, or
high frequency driver (not shown)) 216, 218 via a swivel joint 240,
242 allowing free movement therebetween. The use of swivel joints
232, 234 in connecting the first and second coupling arms 224, 226
to the auxiliary support member 202 allows the first and second
driver assemblies 216, 218 to be folded close to the auxiliary
support member 202 during storage and moved outwardly as shown in
FIG. 1 when the speaker assembly 10 is placed into use. As
discussed above with regard to the base assembly, the swivel joints
are maintained in desired orientations through the implementation
of various locking structures (not shown) known to those skilled in
the art. For example, the locking structure may take the form of
locking pins, compression members, frictional resistance members,
etc.
[0048] An auxiliary member amplifier 244 drives the first and
second drivers 216, 218. The auxiliary member amplifier 244 is
mounted within the auxiliary support member 202 and is covered by a
removable plate 247 for ready access to various control
members/source inputs 249 along the auxiliary member amplifier 244
by a user of the present speaker assembly 10. The auxiliary member
amplifier 244 is electrically coupled to the respective first and
second driver assemblies 216, 218 via wires (not shown) extending
from the auxiliary member amplifier 244, through the auxiliary
support member 202, through the respective first and second support
arms 224, 226 and into the connections of the first driver 216 and
the second driver 218.
[0049] The auxiliary member amplifier 244 further includes a source
connection 246 and a power connection 248. The source connection
246 and power connection 248 are linked to the base member
amplifier 144 via output wires 153, 155 providing a power and
source output from the base member amplifier 144. This is achieved
by extending input wires 253, 255 from the source connection 246
and the power connection 248 of the auxiliary member amplifier 244
to the first end 206 of the auxiliary support member 202. The input
wires 253, 255 are provided with terminal connections 252, 254
shaped and dimensioned for selective coupling with the output wires
153, 155 extending from the base member amplifier 144 to the second
end 108 of the central support member 102. As with the input wires
253, 255 of the auxiliary member amplifier 244, the output wires
153, 155 of the base member amplifier 144 are provided with mating
terminal connections 152, 154 shaped and dimensioned for selective
coupling with the terminal connections 252, 254 of the input wires
253, 255 of the auxiliary member amplifier 244. As those skilled in
the art will appreciate, the wires and connections employed in
linking the base member amplifier to the auxiliary member amplifier
may take various forms, including but not limited to RCA
connections, XLR (extra long run) balanced line connections
(typically 600 Ohm impedance and are used for microphones, etc. in
TV, sound reinforcement and recording studios), optical
connections, USB connections, Firewire connections, Ethernet
connections, as well as integrally formed pin connection structures
commonly used in the electronics industry.
[0050] As shown in accordance with the embodiment disclosed with

support member 202 of the auxiliary speaker assembly 200. The
second end 308 of the auxiliary support member 302 includes a
coupling member 317 shaped and dimensioned to selectively receive
and support an additional auxiliary speaker assembly.
[0051] The auxiliary speaker assembly 300 includes a first support
arm 324 connecting a first driver 316 to the auxiliary support
member 202 and a second support arm 326 connecting a second driver
318 to the auxiliary support member 202. Each of the first and
second support arms 324, 326 includes a first and a second end. The
first ends 328, 330 of the first and second support arms 324, 326
are coupled to the auxiliary support member 202 via a swivel joint
332, 334 allowing free movement therebetween and the second ends
336, 338 of the first and second support arms 324, 326 are
similarly coupled to the respective first and second driver
assemblies (for example, and in accordance with a preferred
embodiment, which is composed of a midrange driver and tweeter, or
high frequency driver (not shown)) 316, 318 via a swivel joint 340,
342 allowing free movement therebetween. As discussed above with
regard to the base assembly, the swivel joints are maintained in
desired orientations through the implementation of various locking
structures (not shown) known to those skilled in the art. For
example, the locking structure may take the form of locking pins,
compression members, frictional resistance members, etc. As with
the auxiliary speaker assembly discussed above, the use of swivel
joints in connecting the first and second coupling arms to the
auxiliary support member allows the first and second drivers to be
folded close to the auxiliary support member during storage and
moved outwardly as shown in FIG. 1 when the speaker assembly 10 is
placed into use.
[0052] An auxiliary member amplifier 344 drives the first and
second driver assemblies 316, 318. This auxiliary member amplifier
344 is substantially similar to the one discussed above. As such,
the auxiliary member amplifier 344 is mounted within the auxiliary
support member 302 and is covered by a removable plate 347 for
ready access to various control members/source inputs 349 along the
auxiliary member amplifier 344 by a user of the present speaker
assembly 10. The auxiliary member amplifier 344 includes a source
connection 346 and a power connection 248. The source connection
246 and power connection 248 are linked to the auxiliary member
amplifier 244 via output wires 257, 259 of the auxiliary member
amplifier 244 providing a power and source output from the
auxiliary member amplifier 244. This is achieved by extending input
wires 357, 359 from the source connection 346 and the power
connection 348 of the auxiliary member amplifier 344 to the first
end 306 of the auxiliary support member 302. The input wires are
provided with terminal connections (not shown) shaped and
dimensioned for selective coupling with the output wires 257, 259
extending from the auxiliary member amplifier 244 to the second end
208 of the central support member 202. As with the input wires 357,
359 of the auxiliary member amplifier 244, the output wires of the
auxiliary member amplifier 244 are provided with mating terminal
connections (not shown) shaped and dimensioned for selective
coupling with the terminal connections 352, 354 of the input wires
of the auxiliary member amplifier 344. As those skilled in the art
will appreciate, the wires and connections employed in linking the
base member amplifier to the auxiliary member amplifier may take
various forms, including but not limited to RCA connections, XLR
(extra long run) connections, optical connections, USB connections,
Firewire connections, Ethernet connections, as well as integrally
formed pin connection structures commonly used in the electronics
industry. Those skilled in the art will appreciate, that because
multiple auxiliary speaker assemblies may be used, auxiliary
speaker assembly 300 (as well as any other auxiliary speaker
assemblies) discussed herein would also include output wires as
disclosed with reference to auxiliary speaker assembly 200.
[0053] Although first and second auxiliary speaker assemblies are
disclosed in accordance with a preferred embodiment, those skilled
in the art will appreciate, that a single auxiliary speaker
assembly or more than two auxiliary speaker assemblies may be
employed without departing from the spirit of the present
invention. In addition, although driver assemblies composed of a
midrange and tweeter are disclosed in accordance with a preferred
embodiment, those skilled the art will appreciate the specifics
drivers employed in the implementation of the present invention may
be varied without departing from the spirit of the present
invention.
[0054] Functionality of the present modular speaker assembly may
further be enhanced by the inclusion of a synchronizable light
source or sources 80, for example utilizing light-emitting diodes,
organic light-emitting diodes, electro-luminescent films, etc.,
such that the amplitude, frequency and harmonic composition of the
music being reproduced is displayed on the surface of the modular
speaker system and varies from dim to intense for amplitude, deep
red for the lowest bass frequencies up through to blue for the
highest treble frequencies. The displays may be concentrically or
coaxially, that is longitudinally, oriented. The light
source/sources may be recessed into a channel or series of channels
for protection during transport, setup and breakdown of the sound
reinforcement assembly.
[0055] In addition, cooling of the present speaker assembly 10 is
enhanced by the inclusion of fan 82 integrated into a removable cap
for placement upon the top auxiliary speaker assembly (in
accordance with the disclosed embodiment, auxiliary speaker
assembly 300). The fan 82 is oriented to draw air from the internal
cavity defined by the base assembly and the auxiliary speaker
assembly(ies), creating a constant, cooling airflow within the
present speaker assembly 10. In accordance with a preferred
embodiment of the present invention, power for the fan may be
provided by either connecting the fan to the power source passing
through the speaker assembly or via battery power. In addition, it
is contemplated many of the components of the speaker assembly will
be manufactured from aluminum which functions as a natural heat
sink.
[0056] Ease of construction and assembly is achieved by making the
base support member 102 and the auxiliary support members 202, 302
with the same diameter. This will allow for the use of similar
materials during construction, and permit versatility in the order
in which various auxiliary speaker assemblies are coupled
together.
[0057] In accordance with an alternate embodiment, and with
reference to FIGS. 7 to 12, the system is provided as a sound
assembly 1000 composed of first and second modular speaker systems
1010, 2010, with digital signal processing and wireless
connectivity as will be described below in greater detail. The
provision of first and second modular speaker systems 1010, 2010
allows a musician to set up and project sound using left and right
(or more) channels for the enjoyment of his or her music.
[0058] The first modular speaker system 1010 and the second modular
speaker system 2010 are substantially the same and each includes
features of the embodiment disclosed with reference to FIGS. 1 to
6. In contrast, however, with the embodiment disclosed with
reference to FIGS. 1 to 6, each of the first and second modular
speaker systems 1010, 2010 is provided with a wireless transceiver
1160, 2160 and an associated digital signal processor 1162, 2162
such that the first and second modular speaker systems 1010, 2010
may communicate for the transfer of information in the processing
of signals for the projection of sound.
[0059] The first and second modular speaker systems 1010, 2010 are
identical and, therefore, only the first modular speaker system
1010 is described herein. The first modular speaker system 1010
includes a base assembly 1100 to which a plurality of auxiliary
speaker assemblies 1200, 1300 may be secured. The base assembly
1100 includes a longitudinally extending, cylindrical, central
support member 1102 and a support leg 1104 extending therefrom in a
manner supporting the central support member 1102 in a generally
upright configuration. The support leg 1104 is cylindrical and
provides a passageway for coupling the various drivers used in
accordance with the present invention with a power source. The
support leg 1104 is pivotally secured to the central support member
1102 allowing the support leg 1104 to collapse onto the central
support member 1102 for compact storage when the present speaker
assembly 1010 is disassembled.
[0060] The central support member 1102 includes a first end 1106
and a second end 1108. The first end 1106 is provided with a planar
support plate 1110 shaped and dimensioned to sit upon a support
surface 1112 supporting the base assembly 1100 in a stable manner
when used in conjunction with the support leg 1104. The second end
1108 of the central support member 1102 includes a coupling member
1114 shaped and dimensioned to selectively receive and support an
auxiliary speaker assembly 1200. In accordance with a preferred
embodiment, the coupling member 1114 is a female coupling member
shaped and dimensioned to receive a similarly shaped male coupling
member 1214 extending from the auxiliary speaker assembly 1200.
[0061] A first woofer 1116 and a second woofer 1118 are secured to
the base assembly 1100. Each of the first and second woofers 1116,
1118 includes a base 1120, 1122 shaped and dimensioned to sit upon
a support surface 1112 in a stable manner taking advantage of the
mass of the woofers 1116, 1118 to significantly lower the whole
assembly's center of gravity. As such, the first and second woofers
1116, 1118 support themselves upon the support surface 1112 while
also adding to the stability of the base assembly 1100 by
functioning as additional legs extending from the central support
member 1102. This adds stability to the entire speaker assembly
1010 and allows for the attachment of additional auxiliary speaker
assemblies in the manner discussed below.
[0062] First and second coupling arms 1124, 1126 extend between the
central support member 1102 and the respective first and second
woofers 1116, 1118. Each of the first and second coupling arms
1124, 1126 includes a first and a second end. The first ends 1128,
1130 of the first and second coupling arms 1124, 1126 are coupled
to the central support member 1102 via a swivel joint 1132, 1134
allowing free movement therebetween and the second ends 1136, 1138
of the first and second coupling arms 1124, 1126 are similarly
coupled to the respectively first and second woofers 1116, 1118 via
a swivel joint 1140, 1142 allowing free movement therebetween.
[0063] Signal transmission and sound reproduction are controlled
and facilitated by the provision of a wireless transceiver 1160, a
digital signal processor 1162 and a base member amplifier 1144. As
is appreciated, the digital signal processor 1162 allows for
"mixing of sound" where the "panning" of the various sources and
"channel assignments" is achieved. In accordance with a preferred
embodiment the wireless transceiver 1160, the digital signal
processor 1162 and a base member amplifier 1144 are mounted within
the central support member 1102. The wireless transceiver 1160, the
digital signal processor 1162 and the base member amplifier 1144
are covered by a cover plate 1145 for ready access by a user of the
present speaker assembly 1010. In accordance with a preferred
embodiment, the cover plate 1145 is slidingly or pivotally secured
to the central support member 1102 to allow access to the base
member amplifier 1144, digital signal processor 1162 and the
wireless transceiver 1160. The sliding or pivotal mounting of the
cover plate 1145 allows for access while not requiring that the
cover plate 1145 be fully removed from the central support member
1102 thus preventing the possibility that the plate might be
misplaced after being removed from the central support member.
[0064] Although the wireless transceiver, digital signal processor
and base member amplifier are disclosed as separate elements, it is
appreciated that the signal processing circuitry of the digital
signal processor, the wireless transceiver and the base assembly
amplifier may be integrated within a unitary housing.
[0065] The wireless transceiver 1160 facilitates the wireless
transmission of audio signals between the first and second modular
speaker systems 1010, 2010, as well as between the first and second
modular speaker systems 1010, 2010 and an audio signal source, for
example, musical instrument, microphone, etc.
[0066] The source signals received by the wireless transceiver 1160
are transmitted to the digital signal processor 1162 where they are
processed in accordance with predetermined protocols. As will be
appreciated based upon the following disclosure, the source signals
are processed by the digital signal processor 1162 using sound and
data processing techniques and distributed to the various drivers
making up the present speaker assembly 1010. The digital signal
processor 1162 includes wired source connections 1164 (discussed
below in greater detail), a power connection 1166 and various
control members 1168. Power for the wireless transceiver 1160 (as
well as the base member amplifier 1144) is provided via the
respective connections between the digital signal processor 1162,
the wireless transceiver 1160 and the base member amplifier 1144.
The power connection 1166 of the digital signal processor 1162 is
linked to an external connection point 1150 within the support leg
1104 via a wire 1151 for connection to a remote power source.
[0067] The wireless transceiver 1160, digital signal processor 1162
and base member amplifier 1144 are covered by the cover plate 1145
and therefore may be readily accessed by users. As such, the signal
processing protocols of the digital signal processor 1162 may be
readily controlled by the user. It is further appreciated wireless
control techniques may be implemented using the wireless
transceiver 1160 as the bridge for transmitting control signals to
the digital signal processor 1162.
[0068] In addition to input from the wireless transceiver 1160, the
digital signal processor 1162 is provided with a wired source
connection 1164 with the ability to receive audio and data source
signals via wired transmission from an audio or data signal source.
In accordance with a preferred embodiment, and in an effort to
simplify set-up of the present first and second modular speaker
systems 1010, 2010, the wired audio source need only be connected
to digital signal processor 1162, 2162 of either the first or
second modular speaker systems 1010, 2010. The appropriate signals
will then be wirelessly transmitted to the other modular speaker
system via the wireless transceivers 1160, 2160.
[0069] Considering the provision of wireless transceivers 1160,
2160 in accordance with the present invention, the source signals
may be processed in a variety of manners to achieve the goals of
the user. For example, the first and second modular speaker systems
1010, 2010 may be simply provided with traditional left and right
stereo signals. More sophisticated scenarios are also possible,
where the various drivers of the first and second modular speaker
systems 1010, 2010 are driven in accordance with highly specific
protocols. In this way, a single modular speaker system (or
multiple modular speaker systems) may be utilized for the
transmission of multiple channels of sound information.
[0070] The processed signals from the digital signal processor
1162, 2162 (that is, for example, voice "mixed" to the center
coming equally from both left and right, guitar coming from one
side, keyboard sounds from the other or played in a stereo mode)
are transmitted to the base member amplifier 1144 which then drives
the first and second woofers 1116, 1118. The base member amplifier
1144 is electrically coupled to the respective first and second
woofers 1116, 1118 via wires (not shown) extending from the base
member amplifier 1144, through the central support member 1102,
through the respective first and second coupling arms 1124, 1126
and into the connections of the first woofer 1116 and the second
woofer 1118.
[0071] The base member amplifier 1144 further includes source
connections 1146 and power connection 1148 coupled to the digital
signal processor 1162, as well as various control members 1149. The
base member amplifier 1144 also provides for adjustment of
crossover points for the different drivers used in the manufacture
of the modular speaker system. It is also appreciated the various
drivers of the modular speaker system could actively or passively
set a crossover point when connected to the modular speaker system.
This would prevent a driver from being blown out by an
incorrect/inappropriate crossover setting.
[0072] As discussed above, the base assembly 1100 is shaped and
dimensioned for supporting one or more auxiliary speaker assemblies
1200, 1300. The first auxiliary speaker assembly 1200 includes a
longitudinally extending, auxiliary support member 1202 having a
first end 1206 and a second end 1208. The first end 1206 includes a
coupling member 1214 shaped and dimensioned for selective
engagement with the coupling member 1114 at the second end 1108 of
the central support member 1102. More particularly, the coupling
member 1214 at the first end 1206 of the auxiliary support member
1202 is a male coupling member shaped and dimensioned for receipt
within the female coupling member 1114 at the second end 1108 of
the central support member 1102 of the base assembly 1100.
[0073] The second end 1208 of the auxiliary support member 1202
includes a coupling member 1215 shaped and dimensioned to
selectively receive and support an additional auxiliary speaker
assembly 1300. As with the respective male and female coupling
members 1214, 1114 of the auxiliary support member 1202 and the
central support member 1102, and in accordance with a preferred
embodiment of the present invention, the coupling member 1215 at
the second end 1208 of the auxiliary support member 1202 is female
coupling member shaped and dimensioned to receive a similarly
shaped male member 1315 extending from another auxiliary speaker
assembly 1300. As with the connection of the base assembly and the
auxiliary speaker assembly, the male and female coupling members
1315, 1215 may further be provided with selective locking
structures for adding to the stability of the connection between
the auxiliary support member 1202 and the auxiliary speaker
assembly 1300.
[0074] The auxiliary speaker assembly 1200 includes a first support
arm 1224 connecting a first driver 1216 to the auxiliary support
member 1202 and a second support arm 1226 connecting a second
driver 1218 to the auxiliary support member 1202. Each of the first
and second support arms 1224, 1226 includes a first and a second
end. The first ends 1228, 1230 of the first and second support arms
1224, 1226 are coupled to the auxiliary support member 1202 via a
swivel joint 1232, 1234 allowing free movement therebetween and the
second ends 1236, 1238 of the first and second support arms 1224,
1226 are similarly coupled to the respective first and second
driver assemblies (for example, and in accordance with a preferred
embodiment, which is composed of a midrange driver and tweeter, or
high frequency driver (not shown)) 1216, 1218 via a swivel joint
1240, 1242 allowing free movement therebetween. The use of swivel
joints 1232, 1234 in connecting the first and second coupling arms
1224, 1226 to the auxiliary support member 1202 allows the first
and second driver assemblies 1216, 1218 to be folded close to the
auxiliary support member 1202 during storage and moved outwardly as
shown in FIG. 7 when the present modular speaker system 1010 is
placed into use.
[0075] An auxiliary member amplifier 1244 drives the first and
second drivers 1216, 1218. The auxiliary member amplifier 1244 is
mounted within the auxiliary support member 1202 and is covered by
a removable plate 1247 for ready access to various control
members/source inputs 1249 along the auxiliary member amplifier
1244 by a user of the present modular speaker system 1010. The
auxiliary member amplifier 1244 is electrically coupled to the
respective first and second driver assemblies 1216, 1218 via wires
(not shown) extending from the auxiliary member amplifier 1244,
through the auxiliary support member 1202, through the respective
first and second support arms 1224, 1226 and into the connections
of the first driver 1216 and the second driver 1218.
[0076] The auxiliary member amplifier 1244 further includes a
source connection 1246 and a power connection 1248. The source
connection 1246 and power connection 1248 are linked to the base
member amplifier 1144 (and ultimately the digital signal processor
1162) via output wires 1153, 1155 providing a power and source
output from the base member amplifier 1144. This is achieved by
extending input wires 1253, 1255 from the source connection 1246
and the power connection 1248 of the auxiliary member amplifier
1244 to the first end 1206 of the auxiliary support member 1202.
The input wires 1253, 1255 are provided with terminal connections
1252, 1254 shaped and dimensioned for selective coupling with the
output wires 1153, 1155 extending from the base member amplifier
1144 to the second end 1108 of the central support member 1102. As
with the input wires 1253, 1255 of the auxiliary member amplifier
1244, the output wires 1153, 1155 of the base member amplifier 1144
are provided with mating terminal connections 1152, 1154 shaped and
dimensioned for selective coupling with the terminal connections
1252, 1254 of the input wires 1253, 1255 of the auxiliary member
amplifier 1244. While the relay of digital signal processor signals
and power is contemplated in accordance with a disclosed
embodiment, it is appreciated the digital signal processor could be
directly wired for connection to the auxiliary member
amplifier.
[0077] The ability of the base member amplifier 1144 to relay
signals and power from the digital signal processor 1162 to the
auxiliary member amplifier is achieved by providing the base member
amplifier 1144 with a microprocessor 1170 controlling the
functioning of the base member amplifier 1144 and allowing it to
function as a "smart" amplifier.
[0078] As shown in accordance with the embodiment disclosed with
reference to FIG. 9, the modular speaker system 1010 is provided
with a second auxiliary speaker assembly 1300. As with the other
auxiliary speaker assembly discussed above, this auxiliary speaker
assembly includes a longitudinally extending, auxiliary support
member 1302 having a first end 1306 a second end 1308. The first
end 1306 includes a male coupling member 1315 shaped and
dimensioned for selective engagement with the female coupling
member 1215 at the second end 1208 of the auxiliary support member
1202. The male coupling member 1315 at the first end 1306 of the
auxiliary support member 1302 is a male coupling member shaped and
dimensioned for receipt within the female coupling member 1215 at
the second end 1208 of the auxiliary support member 1202 of the
auxiliary speaker assembly 1200. The second end 1308 of the
auxiliary support member 1302 includes a coupling member 1317
shaped and dimensioned to selectively receive and support an
additional auxiliary speaker assembly.
[0079] The auxiliary speaker assembly 1300 includes a first support
arm 1324 connecting a first driver 1316 to the auxiliary support
member 1202 and a second support arm 1326 connecting a second
driver 1318 to the auxiliary support member 1202. Each of the first
and second support arms 1324, 1326 includes a first and a second
end. The first ends 1328, 1330 of the first and second support arms
1324, 1326 are coupled to the auxiliary support member 1202 via a
swivel joint 1332, 1334 allowing free movement therebetween and the
second ends 1336, 1338 of the first and second support arms 1324,
1326 are similarly coupled to the respective first and second
driver assemblies (for example, and in accordance with a preferred
embodiment, which is composed of a midrange driver and tweeter, or
high frequency driver (not shown)) 1316, 1318 via a swivel joint
1340, 1342 allowing free movement therebetween.
[0080] An auxiliary member amplifier 1344 drives the first and
second driver assemblies 1316, 1318. This auxiliary member
amplifier 1344 is substantially similar to the one discussed above.
As such, the auxiliary member amplifier 1344 is mounted within the
auxiliary support member 1302 and is covered by a removable plate
1347 for ready access to various control members/source inputs 1349
along the auxiliary member amplifier 1344 by a user of the present
modular speaker system 1010. The auxiliary member amplifier 1344
includes a source connection 1346 and a power connection 1248. The
source connection 1246 and power connection 1248 are linked to the
auxiliary member amplifier 1244 (and ultimately the digital signal
processor 1162) via output wires 1257, 1259 of the auxiliary member
amplifier 1244 providing a power and source output from the
auxiliary member amplifier 1244. While the relay of digital signal
processor signals and power is contemplated in accordance with a
disclosed embodiment, it is appreciated the digital signal
processor could be directly wired for connection to the auxiliary
member amplifier. The transmitting of source signals and power is
achieved by extending input wires 1357, 1359 from the source
connection 1346 and the power connection 1348 of the auxiliary
member amplifier 1344 to the first end 1306 of the auxiliary
support member 1302. The input wires are provided with terminal
connections (not shown) shaped and dimensioned for selective
coupling with the output wires 1257, 1259 extending from the
digital signal processor to the second end 1208 of the central
support member 1202. As with the input wires 1357, 1359 of the
auxiliary member amplifier 1244, the output wires of the auxiliary
member amplifier 1244 are provided with mating terminal connections
(not shown) shaped and dimensioned for selective coupling with the
terminal connections 1352, 1354 of the input wires of the auxiliary
member amplifier 1344.
[0081] The ability of the auxiliary member amplifier 1244 to relay
signals and power from the digital signal processor 1162 to the
auxiliary member amplifier 1344 is achieved by providing the
auxiliary member amplifier 1244 with a microprocessor 1270
controlling the functioning of the auxiliary member amplifier 1244
and allowing it to function as a "smart" amplifier.
[0082] In addition, cooling of the present modular speaker system
1010 is enhanced by the inclusion of fan 1082 integrated into a
removable cap of for placement upon the top auxiliary speaker
assembly (in accordance with the disclosed embodiment, auxiliary
speaker assembly 1300). The fan 1082 is oriented to draw air from
the internal cavity defined by the base assembly and the auxiliary
speaker assembly(ies), creating a constant, cooling airflow within
the present modular speaker system 1010. Ease of construction and
assembly is achieved by making the base support member 1102 and the
auxiliary support members 1202, 1302 with the same diameter. This
will allow for the use of similar materials during construction,
and permit versatility in the order in which various auxiliary
speaker assemblies are coupled together.
[0083] It is further appreciated the additional "slave" units may
be provided for utilization in conjunction with the first and
second modular speaker systems disclosed above. Such "slave" units
would be constructed without signal processors, but would include
amplifiers and transceivers. Consequently, these "slave" units
would operate based upon instructions received from the first
and/or second modular speaker systems.
[0084] It is also appreciated the first and/or second modular
speaker systems may be modified with different types of sound
enhancing modules--made to conform to the physical/electrical
constraints of our preferred embodiment.
[0085] Although various preferred shapes are disclosed in
accordance with a preferred embodiment, for example, cylindrical
shaped support members, those skilled in the art will appreciate
that various shapes may be employed without departing from the
spirit of the present invention.
[0086] While the preferred embodiments have been shown and
described, it will be understood that there is no intent to limit
the invention by such disclosure, but rather, is intended to cover
all modifications and alternate constructions falling within the
spirit and scope of the invention.
